It is an undeniable fact that there are who hate the Pres. based on the color of his skin, and that some of those people are using the current political controversies to voice their disapproval of a black Pres. under the disguise of political ideologies. But, I truly believe that those people make a up a small percentage of the people protesting.
As far as the disrespect you speak of, I am assuming you are referring to the people with the posters of Obama with the Hitler mustache, their actions are no more disrespectful than that of the liberal protesters of GWB who were protesting the war. Further more, both examples are probably just people who are more extreme in their political views and like to go for the shock value of doing more outrageous acts. Either way, those people really don't do their argument justice as those kind of extreme views tend to scare the masses away.
If there are other, more disrespectful acts taking place that I don't know about i'm sorry, I haven't had much time to watch the news lately as I have been really busy with school this semester.
The liberals complain of one reference comparing Obama to Hitler, but forget all of the Photoshops that the left did about Bush/Hitler. A reminder:
